SPECIFICATION forming part of Letters Patent No. 226,359, dated April 6,1880,

Application filed January 26, 1880. I

To all whom it may concern:

Be it known that I, CHARLES SCHTTRMANN, of Indianapolis, in the countyof Marion and State of Indiana, have invented a certain new and usefulDevice for Converting a Reciprocating Motion into a Rotary Motion, ofwhich the following is a specification.

-My invention relates to improvements in which thevertically-reciprocating pump-rod operates in conjunction with a devicefor convertingthe reciprocating motion of the rod into a rotary motion 5and the object of my improvement is to provide thevertically-reciprocatin g pump-rod with a device for operating ahorizontal shaft provided with a pulley, and convert thevertically-reciproeatin g motion of of utilizing the wind-power of themill for runnin g straw-cutters, churns, and other light machinery. Iattain this object by the mechanism illustrated in theaccompanyingdrawings, in which Figure 1 is a front elevation of aportion of a wind-mill frame, showing a front view of the device formingpart of the vertically-reciproeating rod for converting thereciprocating motion of the rod into a rotary motion; and Fig. 2 is aside elevation of the same.

Similarletters refer to similar parts throughout the several views.

The frame T, with vertically reciprocating pump-rod D, may be of anyordinary construction.

The reciprocating rod is represented in the accompanying drawings by theletter D, but is sawed into two parts, and the ends of each part arefirmly secured to the sockets O (J at the top and bottom of the metalliccase (J, thus forming a continuous rod, with the case 0 cmbodied. Thecase 0 is hollow, and provided with a cap, 0 The central portions of thecap 0 and case 0 are each provided with a rectangular slot, a, shown indotted lines in Fig. 1, which is wide enough to permit the case to slideloosely on the shaft B and form a guide, and long enough to allow therod D the full stroke of the windmill crank (not shown) without strikingthe top or bottom of case, between the periphery of the ratchet- I wheelA and walls of said case, is a pawl, G, pivoted at H. The lower end ofthis pawl is held in contact with the ratchet-wheel teeth (I by thespring I, which is securely riveted to the side wall of said case by therivet m.

At the lower right-hand corner of the case 0 is another pawl, K, pivotedat H to the case. The upper end of this pawl is held against theratchet-wheel teeth d by the spring 1, as shown.

The operation of my improved device is as follows The upper end of therod D being connected to a crank of a wind-wheel (not shown) and thewind-wheel being in motion causes a reciprocating motion up and down tothe rod D as the rod D ascends, carrying with it the case 0. The pawl Kcauses the ratchetwheel A, shaft B, and pulley P to rotate at the sametime the pawl G is slipping over the teeth d of the ratchet-wheel. Onthe descending stroke of the rod the pawl G continues the rotary motionof the ratchet, the shaft, and pulley-wheel. Thus the reciprocatingmotion of the rod D, operating in conjunction with the apparatus justdescribed, is converted into a continuous and steady rotary motion.

A belt may connect the wheel P with a straw-cutter, churn, or othermachinery, and

thus utilize the power of the windmill for pur-- poses other than themere lifting of water.

It is obvious that the ratchet-wheel-A (I may be dispensed with, and aplain friction-wheel may be used in lieu thereof, and thatfrictionclutches may be employed in lieu of the pawls, without departingfrom the essence of my invention.

I am aware that prior to my invention areciprocating motion has beenconverted into a In testimony whereof I have signed my 10 rotary motion.I therefore do not claim such name to this specification in the presenceof adevice, broadly; but two subscribing Witnesses.

What I do claim as my invention is- The combination of the rod D D, thecase CHARLES SOHURMANN. G, with cover each having a rectangular opening,a, the pawls G K, springs I I, Witnesses: ratchet-Wheel A c1, shaft B,and. balance-pul- E. O. FRINK,
